If where you bought it have knowledgeable people then maybe they know. I got mine at the Viking dealer inside Joann's and I haven't been back for classes. Actually now that I think about it, when I asked about the classes they said they had, I was told they haven't started them yet.
I'll have to find out. What type of walking foot do you have? I see so many online that I'm not sure which is right. What type of FM foot?
